Yesterday's Gold—Today's Mine
It would seem that we are often indeed destined to repeat history. In terms of gold discovery, even with all the advancements that have been made over the years, it seems we are once again on the cusp of returning to the 1800s world of gold mining.

How to Recognize Hard Rock Gold Ores

There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
Prospecting for Diamonds
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
